Western Australia and Sediments in King Sound

Tan sediments from the Fitzroy River fill King Sound, about 120 km long and with an average width of about 50 km, on the northern coastline of Western Australia. These sediments slowly spread out of the sound and into the Indian Ocean, giving the waters a greenish hue.

Moving down the coast to the southwest, the shoreline takes on a whitish glow. This is due to the white sands of beaches such as Eighty Mile Beach. Also appearing white in color, further inland, are the Rudall River, connected to Lake Dora, with Lake Disappointment to the South. Both lakes are saline, as one might suppose from their white color.
